At the end of the 19th century in the fundamentals of mathematics appeared a crisis. It was caused by the paradoxes found in Cantor’s set theory. One of the ideas a resolving the crisis was intuitionism – one of the constructivist trends in the philosophy of mathematics. Its creator was Brouwer, the main representative was Heyting. In this paper described will be attempt to construct a suitable logic...
By the end of the 19th century, mathematics had become very intensively developed. Mathematical logic became an independent discipline, and in the 1880s Cantor published his work on set theory. All this led to questions about the consistency of mathematical theories and decidability theorems. Therefore, for the second time in the history of mathematics, there emerged a crisis of the basis of mathematics...
